The conversations sidebar shows visual indicators for channel activity.
Visual States
- Bold text — channel has unread user messages
- Numeric badge — shows count of unread messages (e.g., "3")
- Red dot badge — your nickname was mentioned
- Selected background — currently active channel
- Grayed out — channel is muted (no badges shown)
- ⚡ icon + gray — channel is disconnected
Behavior
Switching to a channel resets its unread count and badges. System messages (joins, parts, quits) do not increment the count — only user messages and mentions do. Counts above 99 display as "99+". Muted channels still track unread counts internally — unmuting reveals accumulated indicators.
